In this post I’ll explore how you can use Excel to calculate joint loads, by focusing on the principles you can use in your own spreadsheets. Bolted joints are critical components in various mechanical …

We use our BoltExpert Wrap both as a training tool and to help engineers understand joint mechanics. It works by considering each element of a bolted joint to reveal the root cause of loosening and the …

A brief and to the point summary is provided in these lesson notes and Excel spreadsheets that will provide information that can be used to solve bolted connection design problems and create new …

Units utilized within calculators are either SI or Imperial (some enable both SI and Imperial) and member (you) are responsible for conversions. Ensure that you verify units utilized in excel application meet …

The spreadsheet allows to calculate the forces on the bolts in a bolted connection inserting the coordinates of each bolt composing the joint. The external loads considered in the spreadsheet are …

Excel calculates the preload torque needed to reach the specified preload tension. Excel also calculates the shear capacity remaining in the bolt after pretension is applied.

Our special inspection solutions can include inspecting scheduled maintenance, wheel load balance & levelling, bolt failure diagnostics, handovers, and rail incident safety.

It is not unusual to increase bolt size because the torque tightening method cannot guarentee a minimum preload. The effects of the torque tightening method are shown on the joint diagram below.

The document provides design data for bolt capacity including steel grades, bolt dimensions, plate thickness, material strengths, load values, and equations to calculate shear, tension, bearing, and …

The figure below shows the clamping force acting on the two materials being clamped together by a bolt and nut assembly. Calculating the value of the clamping force depends on the loading condition on …
